Is this item on one of the main Woot sites (home, tech, kids, etc.)? If so, then you don't get any discount at all for buying more than one of an item, and for most of the items you can only purchase three per Woot account.

If the item is over here on the deals.woot.com side, then you'd have to contact the merchant selling the item to ask about any available discounts.
